Answer 1

问题在于 display: none 属性。缩小窗口大小后，您的粘性容器就会被隐藏。但是，当您将浏览器恢复到全窗口时，此属性保持不变。

我建议检查您的 CSS 规则和 JS 对窗口大小调整的处理(如果有)。

编辑:您的标题由于其显示属性而被破坏。 <div style="display: HERE GET'S COMPLICATED;" class="sticky-checkin oteller-sticky"> 。调整大小时，它会检索值none，无论窗口大小如何变化，该值都保持设置。然而还有一件事。如果您向下滚动以显示此 header ，则会将其值设置为block。此时，尝试调整窗口大小，标题将保持不变，直到刷新页面。代码太多，我无法正确调试它，因此请尝试隔离负责 header 显示的代码。
